MakerBot PLA filament is a bioplastic derived from corn. It's guaranteed not to have any heavy metals, phthalates or BPA.
Every filament color is comprehensively quality tested at both 100-micron and 200-micron layer resolutions to verify that the filament will perform every feature that MakerBot MakerWare and MakerBot Desktop software offer.
If you're new to 3D printing, MakerBot PLA filament is a good material to start with because it's easy to use and performs well on most prints.
